La presente invenzione si riferisce ad un dispositivo e metodo di applicazione di nastro biadesivo ad un supporto. The present invention relates to a device and method for applying double-sided adhesive tape to a support.

Stato della tecnica State of the art

Esistono processi industriali in cui è necessario applicare una delle due facce adesive di un nastro biadesivo su un supporto meccanico. There are industrial processes in which it is necessary to apply one of the two adhesive faces of a double-sided tape to a mechanical support.

Tale supporto meccanico, potrà, grazie all’applicazione del nastro biadesivo, essere attaccato ad altri oggetti o parti di essi. This mechanical support can, thanks to the application of the double-sided tape, be attached to other objects or parts of them.

In alcuni di detti processi industriali risulta necessario riscaldare il nastro biadesivo allo scopo di attivarne la superficie adesiva destinata ad attaccarsi a detto supporto. In tal caso si parla di nastro biadesivo termoattivabile. In some of said industrial processes it is necessary to heat the double-sided adhesive tape in order to activate its adhesive surface destined to stick to said support. In this case we speak of heat-activated double-sided tape.

Spesso risulta necessario dover riscaldare anche il supporto, allo scopo di eliminare residui di oli e grassi che ridurrebbero drasticamente il potere adesivo del nastro biadesivo. Often it is also necessary to heat the support, in order to eliminate residues of oils and greases that would drastically reduce the adhesive power of the double-sided tape.

Per determinare questo aumento di temperatura vengono utilizzati dei sistemi di riscaldamento, quali, ad esempio, getti di aria calda o radiazione infrarossa generata da apposite lampade. To determine this temperature increase, heating systems are used, such as, for example, jets of hot air or infrared radiation generated by special lamps.

Tali sistemi devono essere in grado di riscaldare sia di riscaldare il nastro biadesivo senza andare oltre la temperatura di attivazione, altrimenti si rischia di danneggiare la conformazione meccanica del nastro. Infatti, molto spesso i nastri biadesivi sono fatti di materiali plastici che fondono a 150 - 250 °C, a fronte di una temperatura di attivazione del nastro di circa 140 °C. These systems must be able to both heat and heat the double-sided tape without going beyond the activation temperature, otherwise there is a risk of damaging the mechanical conformation of the tape. In fact, very often double-sided adhesive tapes are made of plastic materials that melt at 150 - 250 ° C, compared to an activation temperature of the tape of about 140 ° C.

Si comprende allora quanto sia delicata la procedura di riscaldamento del nastro biadesivo soprattutto se deve essere riscaldato anche il supporto a cui il nastro è destinato ad essere applicato. It is therefore easy to understand how delicate the heating procedure of the double-sided tape is, especially if the support to which the tape is intended to be applied must also be heated.

Tale problema risulta ancora più grave se si tiene presente che il nastro biadesivo deve essere applicato con una certa forza sul supporto e a velocità di scorrimento di 10- 20 metri/minuto ed anche maggiore. This problem is even more serious if one bears in mind that the double-sided adhesive tape must be applied with a certain force on the support and at a sliding speed of 10-20 meters / minute and even higher.

La tecnica nota propone sistemi di guida complessi atti a resistere a forti escursioni termiche. Ad esempio nello scaldare sia il biadesivo che il materiale di supporto le pulegge di guida del nastro e/o del supporto tendono a riscaldarsi per conduzione termica, per cui può accadere che la temperatura delle pulegge di guida giungano ad una temperatura tale da attivare il nastro prima che esso giunga nel punto di applicazione al supporto con un conseguente cattivo risultato. Pertanto, la tecnica nota ricorre, in modo oramai consolidato, all’utilizzo di circuiti di raffreddamento a mezzo di liquido refrigerante che percorrendo canali realizzati all’interno delle pulegge di guida al fine di mantenerle ad una temperatura inferiore a quella limite. The known art proposes complex guiding systems capable of resisting strong thermal excursions. For example, when heating both the double-sided tape and the support material, the guide pulleys of the tape and / or of the support tend to heat up due to thermal conduction, so that the temperature of the guide pulleys may reach a temperature such as to activate the tape. before it reaches the point of application to the support with a consequent bad result. Therefore, the known technique resorts, in a now consolidated way, to the use of cooling circuits by means of refrigerant liquid which along channels made inside the guide pulleys in order to keep them at a temperature below the limit.

Inoltre, il fatto di riscaldare anche il materiale dì supporto fa si che questo si dilati per ritornare alle dimensioni originali a raffreddamento compiuto. Il differente coefficiente di dilatazione termica tra il nastro biadesivo ed il supporto determina stati tensionali a raffreddamento compiuto e la comparsa di grinze sul sullo strato di protezione, detto in lingua anglosassone liner, della faccia adesiva del nastro biadesivo non interessata in questa fase di lavorazione. Detti tensionamenti meccanici possono essere particolarmente problematici quando il nastro biadesivo viene applicato a supporti di materiale elastico tipo, ad esempio, guarnizioni in gomma. Inoltre, per poter ulteriormente manipolare il prodotto lavorato comprendente il supporto a cui è stato applicato il nastro biadesivo è necessario attendere il tempo di raffreddamento del prodotto, con ulteriori accorgimenti tecnici che determinano ulteriori costi. Furthermore, the fact that the support material is also heated causes it to expand to return to its original size after cooling. The different coefficient of thermal expansion between the double-sided adhesive tape and the support determines stress states after cooling and the appearance of wrinkles on the protective layer, called in Anglo-Saxon liner, of the adhesive face of the double-sided tape not involved in this processing phase. Said mechanical tensioning can be particularly problematic when the double-sided adhesive tape is applied to supports of elastic material such as, for example, rubber gaskets. Furthermore, in order to be able to further manipulate the processed product including the support to which the double-sided tape has been applied, it is necessary to wait for the cooling time of the product, with further technical measures which determine further costs.

Dunque, la tecnica nota, malgrado la predisposizione di complessi sistemi di raffreddamento delle pulegge di guida del nastro biadesivo ed, eventualmente, dei supporto, non è in grado di garantire un risultato costantemente accettabile, soprattutto se si pensa che le caratteristiche fisico-meccaniche dei prodotti possono variare molto in relazione ai fornitori e alle diverse partite, per cui, questi processi industriali necessitano di un periodo di affinamento delle regolazioni di funzionamento delle macchine che comportano una almeno temporanea produzione di prodotti difettosi. Therefore, the known technique, despite the provision of complex cooling systems for the guide pulleys of the double-sided tape and, possibly, of the support, is not able to guarantee a consistently acceptable result, especially if one considers that the physical-mechanical characteristics of the products can vary a lot in relation to the suppliers and the different batches, so these industrial processes require a period of refinement of the operating regulations of the machines that involve at least a temporary production of defective products.

Sommario dell'invenzione Summary of the invention

Scopo della presente invenzione è quello di fornire un dispositivo di applicazione di nastro biadesivo ad un supporto atto a risolvere il suddetto problema di riscaldamento non corretto o prematuro del nastro biadesivo e/o dell’eccessiva dilatazione termica del materiale di supporto. The purpose of the present invention is to provide a device for applying double-sided tape to a support designed to solve the aforementioned problem of incorrect or premature heating of the double-sided tape and / or excessive thermal expansion of the support material.

E' oggetto della presente invenzione un dispositivo di applicazione di nastro biadesivo ad un supporto che, conformemente alla rivendicazione 1 , comprende una sorgente di calore atta ad attivare il nastro biadesivo e a riscaldare il supporto caratterizzato dal fatto che detta sorgente è un laser. The object of the present invention is a device for applying double-sided adhesive tape to a support which, according to claim 1, comprises a heat source adapted to activate the double-sided adhesive tape and to heat the support characterized in that said source is a laser.

L’impiego di una sorgente laser per riscaldare il nastro biadesivo, consente di produrre un riscaldamento locale delle sole parti interessate al riscaldamento e nel momento immediatamente prima all’applicazione nel nastro biadesivo al supporto, eliminando detti problemi di riscaldamento prematuro per conduzione di mezzi e pulegge di guida del nastro biadesivo oppure del supporto a cui il nastro è destinato ad essere applicato. The use of a laser source to heat the double-sided tape, allows to produce a local heating only of the parts involved in the heating and in the moment immediately before the application in the double-sided tape to the support, eliminating said problems of premature heating due to the conduction of media and guide pulleys of the double-sided adhesive tape or of the support to which the tape is intended to be applied.

Conseguentemente alla soluzione presentata, si rende possibile semplificare i mezzi di guida e trascinamento del nastro biadesivo e del supporto, potendosi eliminare i relativi sistemi di raffreddamento a liquido con notevole risparmio dei costi di costruzione degli impianti e della relativa manutenzione. As a consequence of the solution presented, it is possible to simplify the guiding and driving means of the double-sided adhesive tape and of the support, since the relative liquid cooling systems can be eliminated with considerable savings in the construction costs of the plants and the relative maintenance.

Secondo un altro aspetto dell’invenzione detto dispositivo può comprendere una sorgente laser atta a illuminare riscaldando contemporaneamente il nastro biadesivo ed il supporto, oppure almeno una prima sorgente laser atta a riscaldare attivando il nastro biadesivo ed almeno una seconda sorgente laser atta a riscaldare il materiale di supporto. According to another aspect of the invention, said device may comprise a laser source adapted to illuminate while simultaneously heating the double-sided adhesive tape and the support, or at least a first laser source adapted to heat by activating the double-sided tape and at least a second laser source adapted to heat the material. support.

According to a further aspect of the present invention, the present invention also relates, according to claim 5, to a method of applying a double-sided adhesive tape to a support comprising the procedure of activating the double-sided adhesive tape by means of a laser source.

Ulteriori caratteristiche e vantaggi dell'invenzione risulteranno maggiormente evidenti alla luce della descrizione dettagliata di forme di realizzazione preferite, ma non esclusive, di un dispositivo di applicazione di nastro biadesivo ad un supporto, illustrato a titolo esemplificativo e non limitativo, con l’ausilio delle unite tavole di disegno in cui: Further characteristics and advantages of the invention will become more evident in the light of the detailed description of preferred but not exclusive embodiments of a device for applying double-sided adhesive tape to a support, illustrated by way of non-limiting example, with the aid of the merge drawing boards where:

la Fig. 2 rappresenta schematicamente un variante del trovato comprendente due sorgenti laser. Fig. 2 schematically represents a variant of the invention comprising two laser sources.

Descrizione in dettaglio di una forma di realizzazione preferita dell'invenzione Un dispositivo di applicazione di un nastro biadesivo conforme col presente trovato comprende una prima puleggia 4 di guida del nastro biadesivo 2 contrapposta con una seconda puleggia 5 di guida del supporto 3 e una sorgente laser 1 atta a proiettare un fascio laser 11. Detailed description of a preferred embodiment of the invention A device for applying a double-sided adhesive tape according to the present invention comprises a first guide pulley 4 for the double-sided adhesive tape 2 opposed to a second guide pulley 5 for the support 3 and a laser source 1 adapted to project a laser beam 11.

Dette pulegge contrapposte sono accostate in modo da comprimere, durante il loro movimento indicato dalle frecce, il nastro biadesivo sul supporto. Il fascio laser 11 è atto a colpire sia il nastro biadesivo che il supporto poco prima che i due vengano compressi l’uno sull’altro da dette pulegge contrapposte. Il prodotto ottenuto 23 rappresenta il supporto 3 con applicato il nastro biadesivo 2. Said opposite pulleys are placed side by side so as to compress, during their movement indicated by the arrows, the double-sided adhesive tape on the support. The laser beam 11 is able to hit both the double-sided tape and the support just before the two are compressed on each other by said opposing pulleys. The obtained product 23 represents the support 3 with the double-sided adhesive tape 2 applied.

In sostanza il fascio laser ha un sufficiente diametro per poter colpire contemporaneamente il biadesivo e il materiale di supporto direttamente nella zona in cui essi vengono a contatto. Il fascio laser è in grado di scaldare molto di più e soprattutto in modo regolare e con temperatura controllata le superfici dei due materiali. Per questo motivo e possibile bruciare i depositi oleosi presenti sulla superficie del materiale di supporto senza scaldarlo internamente e di conseguenza modificare le dimensioni meccaniche di esso. Inoltre essendo il fascio laser puntato solamente sulla zona voluta, non si provoca il riscaldamento della puleggia di guida del biadesivo e del liner del biadesivo stesso, permettendo di eliminare i sistemi di raffreddamento normalmente utilizzati con una notevole semplificazione del l’intero sistema. Basically, the laser beam has a sufficient diameter to be able to simultaneously strike the double-sided adhesive and the support material directly in the area where they come into contact. The laser beam is able to heat the surfaces of the two materials much more and above all in a regular way and with controlled temperature. For this reason it is possible to burn the oily deposits present on the surface of the support material without heating it internally and consequently modify its mechanical dimensions. Furthermore, since the laser beam is aimed only at the desired area, the guide pulley of the double-sided adhesive and the liner of the double-sided adhesive itself are not heated, allowing to eliminate the cooling systems normally used with a considerable simplification of the entire system.

Secondo un’altra variante, conformemente alla figura 2, le sorgenti laser sono due, cioè 1 e 1’, di cui una prima sorgente 1 è predisposta in modo che il suo fascio laser 11 colpisca il nastro biadesivo 2 ed una seconda sorgente laser 1’ predisposta in modo che il proprio fascio laser 11’ colpisca il supporto 3. According to another variant, according to Figure 2, there are two laser sources, namely 1 and 1 ', of which a first source 1 is arranged so that its laser beam 11 strikes the double-sided tape 2 and a second laser source 1 'arranged so that its own laser beam 11' hits the support 3.

La velocità di rotazione delle due pulegge e la pressione esercitata da esse sul punto di contatto tra biadesivo e materiale di supporto, sono regolabili. The rotation speed of the two pulleys and the pressure exerted by them on the contact point between the double-sided tape and the support material are adjustable.

Utilizzando un fascio laser è possibile garantire costantemente la temperatura di 140 °C sulla superficie del biadesivo termoattivabile, in quanto la potenza del laser può dipendere in tempo reale dalla velocità di scorrimento del materiale. Viene utilizzato un trasduttore di velocità, detto encoder, per rendere la potenza direttamente proporzionale alla velocità. Quest’ultima può anche dipendere da sensori ottici di temperatura direzionati verso il punto di contatto ed atti a misurare la temperatura superficiale del nastro biadesivo e/o del supporto. Using a laser beam it is possible to constantly guarantee the temperature of 140 ° C on the surface of the thermo-activated double-sided adhesive, as the laser power can depend in real time on the sliding speed of the material. A speed transducer, called an encoder, is used to make the power directly proportional to the speed. The latter can also depend on optical temperature sensors directed towards the contact point and able to measure the surface temperature of the double-sided tape and / or support.

Inoltre il diametro del fascio laser può essere variato anch’esso al variare delle applicazioni. Furthermore, the diameter of the laser beam can also be varied as the applications vary.

Il prodotto ottenuto 23 in uscita da dette pulegge contrapposte, ritorna quasi immediatamente alla temperatura ambiente, con notevole riduzione di problematiche di arricciamento e tensionamento meccanico tra i due materiali uniti e con la possibilità di essere maneggiato senza particolari cautele. The product obtained 23 exiting said opposing pulleys almost immediately returns to ambient temperature, with a considerable reduction in the problems of curling and mechanical tensioning between the two joined materials and with the possibility of being handled without particular precautions.

La sorgente laser è un’apparecchiatura dalle dimensioni limitate che trova facile alloggiamento in qualsiasi posizione e che può operare a parecchi millimetri di distanza dal punto in cui il fascio laser è puntato. The laser source is a device with limited dimensions that can easily be housed in any position and that can operate at several millimeters away from the point where the laser beam is aimed.

Vantaggiosamente, la soluzione proposta consente di eliminare la fase di preriscaldamento del nastro biadesivo e/o del supposto, garantendo la corretta temperatura di attivazione del nastro biadesivo immediatamente prima della sua applicazione al supporto senza alzare la temperatura degli elementi dell’impianto a contatto con il nastro biadesivo o con il supporto. Advantageously, the proposed solution allows to eliminate the preheating phase of the double-sided tape and / or the suppository, ensuring the correct activation temperature of the double-sided tape immediately before its application to the support without raising the temperature of the elements of the system in contact with the double sided tape or with backing.

Sono chiari i vantaggi derivanti dall’applicazione della presente invenzione: The advantages deriving from the application of this invention are clear:

- eliminazione dell’operazione di preriscaldamento del supporto, - elimination of the support preheating operation,

- maggiore controllo della temperatura nel punto/momento di applicazione del nastro biadesivo al supporto, - greater temperature control at the point / moment of application of the double-sided tape to the substrate,

- circoscrizione del riscaldamento alle sole zone di applicazione del nastro biadesivo e del supporto, - heating district only to the areas of application of the double-sided adhesive tape and the support,

- eliminazione dei sistemi di raffreddamento delle pulegge di guida originariamente destinato a non influenzare il punto/momento di attivazione del collante presente sul nastro biadesivo, - elimination of the cooling systems of the guide pulleys originally intended not to influence the point / moment of activation of the glue present on the double-sided tape,

- maggiore velocità di esecuzione dell’applicazione del nastro biadesivo, dovuta alla maggiore incisività e selettività del fascio laser rispetto ai sistemi noti. - greater speed of execution of the application of the double-sided tape, due to the greater incisiveness and selectivity of the laser beam compared to known systems.

Gli elementi e le caratteristiche illustrate nelle diverse forme di realizzazione preferite possono essere combinate senza peraltro uscire dall’ambito di protezione della presente domanda. The elements and characteristics illustrated in the various preferred embodiments can be combined without however departing from the scope of protection of the present application.
